Using Lasers to Diagnose Abnormal Tissue

12816488_SIn recent posts, we have discussed the implications that lasers have in military technology.

This of course means weapons, which can unsettle a lot of people, and with good reason: since we are a society reared on sci-fi movies, it can be difficult separating lasers from destruction.

How many times have you seen a laser gun used on the silver screen?

Perhaps in the hands of strange aliens seeking to take over the earth – how they pull the trigger and we humans are suddenly transformed into dust and bones.

Then there is the Death Star, the famous instrument of oppressive government control – in Star Wars, there would be no Galactic Empire if it weren’t for the Death Star instilling fear in hearts and minds across the galaxy.

We can understand why some of you may not have the most uplifting view of laser technology, but this news story might change up your tune.

According to this BBC article, lasers can detect brain tumor cells during surgery.

Fergus Walsh writes:

“Surgeons in London have used lasers to diagnose abnormal tissue during an operation to remove a brain tumour for the first time in Europe. The non-invasive technique measures light reflected off tissue to determine whether it is cancerous or healthy.”

Such a technique needs to be precise and even that is understating it.  Removing healthy tissue can, and most likely will, cause permanent damage to the brain.

This is a life or death kind of situation and lasers are necessary for their precision and efficiency, making it easier for surgeons to remove all abnormal tissues without touching any of the healthy cells.

This non-invasive technique is definitely the future or as neurosurgeon Babar Vagas puts it, “Optical technologies like this are the future.

They are fast and don’t destroy any tissue and could be used during many types of cancer surgery or when dealing with infection like a brain abscess.”

At Seiffert Industrial, we are excited to see where this technique is heading as it will save many lives. It also helps remove the stigma that lasers are meant for only destruction.
